Currently available on Impulse is Beta1 of GCII version 2.0 (we're shooting for only one major Beta, but there may be more).
I'll keep exposition to a minimum, so here's that list of remaining features you'll be receiving...
New Negotiation Options
Tech Brokering is a game setup option that restricts the trading of technologies to only those you've personally researched. This keeps tech-trade-spam to a minimum and gives some extra muscle to races more technologically inclined.
Trading of fleets has also been added, so now you can gather up all the ships you want to unload and send them off with ease.
All Campaigns Playable
It took some tweaking, but we finally got the Dreadlord and Dark Avatar campaigns working directly in Twilight of the Arnor. (I don't believe this made it in for today's build.)
Arnorian Ship Style
With the final build of 2.0 you'll have full access to the ship style of the Arnorians.
Manual
Yes, the manual has been update with all the 2.0 features. Sorry for the wait.
Feedback
We're now at the stage where the players get to step in and beat up our creation Take 2.0 for a couple of laps, let us know how it runs, and give us your feedback. Enjoy!
